Probably the talk of NYC is the High Line which recently opened its second section. This is a wonderfully designed and landscaped strip of public space, atop an abandoned elevated freight railway, which opened in 2009. With the second phase opened you can walk from 30th and 10th all the way down to 12th. It is like an elevated park, nicely landscaped, with great views of old buildings and new contemporary high rise apartments. It is attracting two million visitors a year. At the southern end will be a new Renzo Piano designed branch of the Whitney Museum which is to open in 2015. You pass by buildings by architects Frank Gehry, Jean Nouvel and Shigeru Ban plus many galleries, food trucks and restaurants. Stop by Chelsea Market which is one of the highlights along the way.
